What we do
High-efficiency tankless installs and tank-to-tankless conversions — sized right for our cold Northwest groundwater. Endless hot water, lower energy bills.
Standard tank and high-efficiency hybrid (heat-pump) units in electric, natural gas, and propane — most swaps done in a single visit, hauled away clean.
Boiler installation, repair, and replacement for home heating and hot water — diagnosed and fixed right, not guessed at.
Manufacturer-recommended yearly service for every unit — especially gas tankless heaters, which need annual descaling to protect the warranty. Flushes and tune-ups for tanks, hybrids, and boilers too.
Lukewarm showers, rusty water, rumbling, pilot problems — honest repair-or-replace advice, and we prioritize no-hot-water calls.
Multi-unit and commercial water heater and boiler work — from apartment buildings to shops — scheduled around your tenants and hours.
